There are several factors that influence our perception of laughter and our ability to identify group members. Some of these factors are different from those that influence the type of laughter we produce. For example, we may perceive laughter differently if we laugh when we are with an out-group member, which may explain why we perceive laughter as more positive when we are among other members of the same group. Thus, it is important to include both measures of laughter to understand group identification and perceived positivity.
